Navionics mapping question

[pimplepounder]

I have Navionics Premium on my Humminbird.. I love it. Very accurate. I fish Erie mostly, but I have yet to find a body of public water in Ohio, Indiana or Michigan that it doesnt have in its software. Charting and marking is easy. Not sure on the other program you mentioned. my 2 cents

I'm interested in responses to this, as well. I have a Lowrance Gen 2 Touch and currently have a Navionics Lake Insight chip and I think it's just OK. I've heard others rave about the Lakemaster chip, but not exactly sure if it'll work in my Gen 2.

Navionics does not make Lake insight, think you may be a little confused. You may have Nautic insight but that's not Navionics, that was lowrance and now is Cmap.

To the OP, i run two chips in my setup, Lake insight pro for inland lakes and when i fish the great lakes i switch to Navionics+. Navionics is alot better out on Erie and Michigan.
